Re: C43/C47 Bug Reports

‘This is most likely a bug in the firmware…’ displays C47

MOD -> SYSTEM

Are you sure?

( here DO NOT respond to the question as yet )

Just press UP or DOWN key.

Re: C43/C47 Bug Reports

Continuing to explore C47

Hard Fault - looks repeatable
No special configuration and RESET.

CAT -> MENUS -> MVAR = Hard Fault

Re: C43/C47 Bug Reports

Thanks dlachieze and Jaco.
This worked. now I am curious about eRPN :-)

I realized eRPN was a default choice in MODE as was F.124.
although I had selected F.1234, my preference, it was reset to F.124 after the Aug update.

Re: C47 Performance on DM42 hardware

Jaco,

I confirm your results.

Starting point in i% makes a diff. —- number of iterations.

When on power I match your results.
Without ext power with 1e99 starting position it takes forever.

Re: C47 Performance on DM42 hardware

12c Platinum 25th year Anniversary

PV -6000
PMT 0
FV 10000
N 32
—- > i%. = 1.61 * 4 = 6.44

With C47 on DM42:

Per 4
—- > i% = 6.44

Basic Interest rate iterative calculation is instant on 12c Plat.
C47 takes 4s appx.

I’d like to think that verbose iteration on the UI is playing a role.

Re: WP43 News

Thanks for reminding.. I thought the software base is the same. I will move it to C47, regardless.

Re: WP43 News

I Installed C47 on my DM42 this past weekend and am warming up to it for Matrix calculations in data science domain. However having used 12c for so long I tried a few examples to see how it does in comparison. Included the examples from the ref material too. 1. TVM in C47 is slow 2. variables that r...
